onsemi NCN26010XMNEVK Evaluation Kit
An innovative new hardware and software combo designed for industrial Ethernet
The onsemi NCN26010XMNEVK 10BASE-T1S MACPHY evaluation kit is a set of PCBs designed to allow customers access to their NCN26010 SPI enabled 10BASE-T1S MACPHY.
Its main purpose is to demonstrate the MACPHYs basic functionality and doubles as a lab tool to allow customers to develop their own embedded software drivers for the NCN26010 device.
The evaluation kit consists of:
The NCN26010BMNEVB bridge board
The NCN26010XMNEVB 10BASE-T1S evaluation board
Featured Product
NCN26010: 10Base-T1S Product Overview
The onsemi NCN26010 device is an IEEE 802.3cg compliant Ethernet Transceiver including a Media Access Controller (MAC), a PLCA Reconciliation Sublayer (RS) and a 10BASE−T1S PHY designed for industrial multi−drop Ethernet. It provides all physical layer functions needed to transmit and receive data over a single unshielded twisted pair. NCN26010 communicates to host MCUs via Open Alliance MACPHY SPI protocol.
Features
Enhanced Noise Immunity Mode:
- ENI extends the noise immunity to values well above the IEEE T1S standard
- Allows the NCN26010 to withstand worst-case DPI and BCI immunity tests
- Significantly improves the network reach when enabled, almost 2X better than competition
- Unique to NCN26010
Lowest Line Pin Capacitance:
- Best-in-class line pin capacitance allows for the highest number of nodes per segment.
- The NCN26010 supports up to 40 nodes on a 25-meter segment, well above the IEEE minimum standard
- Lowers cabling, connector, and installation costs
Collision Detection Masking:
- Masking detected collisions allows operation in noisy conditions
- Prevents false collision detection in high-noise environments
- When used in conjunction with ENI, the NCNS26010 has unparalleled noise tolerance
PLCA Precedence Mode:
- Lower PLCA ID's get precedence over higher ones
- Provides arbitration similar to CAN: The Coordinator (i.e., the head node) sends a new beacon once any station transmits
- Unique to NCN26010
Physical Layer collision avoidance PLCA:
- Allows higher throughput in multi-drop topologies
Two Configurable Digital Outputs that can Drive Low Current LEDs:
- Supports systems where up to two LEDs can provide status indicators
Open Alliance Compatible SPI Interface:
- Conforms to Open Alliance TC6 specs for Configuration and Data Frames to Host MCUs
MAC Address Filtering:
- By filtering frames based on the destination address, Ethernet frames not intended for a certain node are not processed by the host, thus reducing the load
- The MAC will see the frame, process the address, drop it based on the filter criteria, and the host will not need to handle it
Supports IEEE802.3 CSMA/CD Collision Detection
- PLCA mode will default to CSMA/CD collision detection, if needed
